ABSTRACT:
A self-clocking digital position sensor having a main optical transmission line to which are coupled a multiplicity of branch optical transmission lines each of which is for transmitting one bit of position data. The branch transmission lines may be of unequal length or sequentially coupled along the main transmission line to provide a position data sequence of optical pulses reflected from a position coded device at an end terminal of the main transmission line for each optical pulse incident thereto.
